Low-Temperature Differential Scanning Calorimetry of Polysiloxanes

Abstract

Low-temperature differential scanning calorimetry (DSC) was used to determine the temperature region of glass formation or the crystallization of polysiloxanes or both. Research- and commercial-grade polysiloxanes were characterized by DSC to determine where significant physical property changes, such as embrittlement or shrinkage, had occurred. The effect of the thermal history, cooling-heating rate, and molecular weight distribution on thermodynamic behavior was investigated. An illustrative example of the failure analysis of a low-temperature adhesive used on a solar panel is included.
